BACKGROUND OF THE INVENTION

1. Field of the Invention

The present invention relates to a release buckle for coupling or decoupling a band used in a bag, a sack, clothing and the like for carrying articles, and more particularly to, a release buckle in which a fitting hook may be coupled in or separated from a fixing base simply and compact and clean images may be created.

2. Discussion of Related Art

In general, such a release buckle includes a fixing base to be fixed to a surface of an article and a fitting hook detachably coupled with the fixing base.

Conventionally, the release buckle is provided with an insertion part for inserting and coupling the fitting hook in a fitting hook coupling part of the fixing base, wherein the insertion part is formed with holding holes at both sides thereof.

The fitting hook includes a coupling part provided with elastic holding protrusions on both sides thereof for side release SR type coupling with the fixing base. Further, the fitting hook includes a coupling part provided with an elastic holding protrusion at an upper end thereof, so that the elastic holding protrusion at the upper end of the insertion part is inserted into a holding hole complementarily provided at an upper end of the insertion part of the fixing base for front release FR type coupling with the fixing base.

The prior art release buckles as above have, however, a disadvantage that the decoupling of the fitting hook from the fixing base is complicated since the elastic holding protrusions should be pressed by fingers while the fixing base is held by a hand so as to release the holding state of the elastic holding protrusions from the holding holes of the fixing base.

Further, a user should use both of his hands necessarily but this is very inconvenient especially in wintertime since the user wears thick gloves and holding and separation of the fixing base and the fitting hook are difficult when the user wears the gloves.

Furthermore, according to the prior art release buckles, only a part of the fitting hook is inserted and coupled in the fixing base, so that an entire size of the release buckle in the coupling state between the fitting hook and the fixing base becomes large to spoil clean and compact images thereof.

In addition, the elastic holding protrusions are apt to be damaged during use, making durability of the release buckle weak.

The insertion part of the fitting hook is pushed downward via the upper end of the fixing base to be inserted and coupled in the fixing base, and pulled up to be separated from the fixing base. Therefore, if the fitting hook is applied with tension unexpectedly in a direction to pull up the fitting hook while the coupling state of the elastic holding protrusion is not good, the fitting hook may be separated from the fixing base easily, so that the fixing base and the fitting hook cannot be kept in a stable coupling state any more.

SUMMARY OF THE INVENTION

Therefore, the present invention is derived to resolve the above and any other disadvantages of the prior art.

According to the present invention, there is an object to provide a release buckle, in which a fitting hook may be coupled in or decoupled from a fixing base simply while being kept in a coupling state with the fixing base with improved stability, wherein the release buckle is free from the damage possibly generated during use in the prior art.

According to the present invention, there is another object to provide a release buckle, in which a fitting hook is entirely inserted into a fixing base, so that a coupling state between the fitting hook and the fixing base may be improved, creating clean and compact images.

In order to achieve the above objects, according to the present invention, there is provided a release buckle including a fixing base formed with protrusion parts on both sides of a front surface thereof with fitting hook guide coupling grooves, and a fitting hook inserted into a lower part or a side part of the fixing base to be positioned in the fixing base entirely.

Therefore, the fitting hook may be inserted into or separated from the fixing base simply, and kept in a more stabilized state in the fixing base when inserted.

Furthermore, the release buckle is removed from the damage caused during the use thereof.

According to the present invention, a release buckle includes a fixing base 10 having protrusion parts 11 formed at both sides of a front surface thereof, the protrusion parts 11 having fitting hook guide coupling grooves 12 formed with inlets at lower parts thereof, and

a fitting hook 20 formed with at least one or more band connection holes 21 to connect a band W, wherein the fitting hook 20 is inserted into a lower part of the fixing base to be positioned in the fixing base 10 entirely and has both side ends detachably coupled in the guide coupling grooves 12 of the protrusion parts 11 of the fixing base.

Referring to the preferred embodiments of the present invention as shown in the above drawings, a fitting hook 20 is protrudedly formed with a handle protrusion 22 at a front upper end, so that the fitting hook 20 may be moved easily by holding the handle protrusion 22. Further, the fitting hook 20 is formed with two band connection holes 21, so that the band W may be controlled in its connection length freely.

According to the first preferred embodiment of the present invention as shown in FIG. 1 to FIG. 4, a fixing base 10 is provided with a joining flange 13 at its outer periphery, and the joining flange 13 is formed with a sewing groove 14 for mounting the fixing base 10 to a surface of an article P such as a sack or a bag by sewing.

According to the second preferred embodiment of the present invention as shown in FIG. 5 to FIG. 8, a fixing base 10 is provided with a band connection hole 15 at a lower center thereof, and a band W′, which is connected to the band connection hole 15, is mounted to the surface of the article P by sewing.

In the first and second preferred embodiments of the present invention as described above, the fixing base 10 is provided with a rectangular opening 16 at an upper center thereof and a holding protrusion part 17 is formed at a lower front end of the opening 16, so that the band W coupled with the fitting hook 20 is captured and supported by the holding protrusion part 17 as the band W passes beyond the holding protrusion part 17. Therefore, the coupling state of the fitting hook 20 may be kept stably.

According to the third preferred embodiment of the present invention as shown in FIG. 9 to FIG. 11, the fixing bases 10 are mounted to vertical bands W′ which are respectively mounted to front surfaces of a pair of shoulder straps M, and a fitting hook 20 is mounted to an end of a horizontal band W, of which the other end is fixed to one of the fixing bases 10 respectively mounted to the vertical bands.

In the third preferred embodiment of the present invention, the other fixing base 10 is formed with band connection holes 18 at both side ends to connect the vertical band W′ and another band connection hole 19 in the center to connect the horizontal band W.

In addition, according to the third preferred embodiment of the present invention, the other fixing base 10 is formed with a holding protrusion 17 a in the center of a front lower end and the fitting hook 20 is formed with a corresponding holding groove 23 in the center of a lower end of a rear surface, so that the holding protrusion 17 a of the other fixing base 10 is coupled in the holding groove 23 of the fitting hook 20 when coupling the fitting hook 20 with the other fixing base 10. Therefore, the fitting hook 20 is kept stably as being coupled with the other fixing base 10.

In the present invention described as above, when coupling the fitting hook 20 with the fixing base 10 in the vertical direction as disclosed in the first and second embodiments, the inlets of the fitting hook guide coupling grooves 12 formed at the both protrusion parts 11 of the fixing base 10 are positioned at the lower parts so as to pull up the fitting hook 20 from the lower part of the fixing base 10.

When separating the fitting hook 20 from the fixing base 10, the fitting hook 20 is pulled down to the lower part of the fixing base 10.

In addition, when coupling the fitting hook 20 with the other fixing base 10 in the horizontal direction as disclosed in the third embodiment, the fitting hook 20 is pushed outside the other fixing base 10 inward. When separating the fitting hook 20 from the other fixing base 10, the fitting hook 20 is pushed from an inside of the other fixing base 10 outward.

In other words, when coupling the fitting hook 20 to the other fixing base 10, the fitting hook 20 is positioned at the lower part or the side part of the fixing base 10 by a hand and then pushed toward the other fixing base 10 by the hand while the fixing base 10 is held by another hand. When decoupling the fitting hook 20 from the fixing base 10, the fitting hook 20 is pushed toward the outside of the fixing base 10 by one hand while fixing the fixing base 10 with the other hand.

According to the present invention as described above, it is not necessary to release the holding state between the fitting hook and the fixing base by using fingers in advance to separate the fitting hook from the fixing base, which has been carried out in the prior art release buckles in the SR or FR coupling type. Therefore, the fitting hook 20 may be separated from the fixing base 10 conveniently without carrying out the releasing work by using the fingers. Especially, it becomes possible to couple or decouple the fitting hook 20 with or from the fixing base 10 while wearing thick gloves in wintertime.

In addition, according to the present invention, as the fitting hook 20 is applied with by the band W coupled with the fitting hook 20 in the direction to pull the fitting hook 20 upward or laterally in the condition that the fitting hook 20 is coupled with the fixing base 10, the fitting hook 20 becomes coupled with the fixing base 10 more tightly, so that the coupling state between the fitting hook 20 and the fixing base 10 becomes kept more stably.

Further, the fitting hook 20 coupled with the fixing base 10 is positioned in the fixing base 10 entirely, so that an entire area of the release buckle in the coupled state becomes reduced, creating compact and clean images.

According to the present invention as described above, the fixing base is formed with the protrusion parts at both sides of the front surface with the fitting hook guide coupling grooves and the fitting hook 20 is inserted into the fixing base from the lower part of the fixing base 10 to be positioned in the fixing base 10 entirely.

In the present invention, the releasing work for releasing the holding state of the fitting hook 20 by using fingers, which has been carried out in the prior art release buckle in advance to separate the fitting hook from the fixing base 10, is not necessary any more.

Therefore, the fitting hook 20 may be separated more conveniently. Especially the fitting hook 20 may be coupled with or decoupled from the fixing base 10 more conveniently by using hands wearing thick gloves in wintertime. In addition, the coupling state of the fitting hook 20 may be kept more stably and the entire area of the release buckle in the coupled state may be reduced, so that the compact and clean images may be created.
